The horse who could do maths — and what he was really reading

In early 1900s Berlin, a horse called Clever Hans appeared to do arithmetic. Ask him four plus three and he would tap his hoof seven times, then stop. He answered questions about dates, music, spelling. Crowds adored him.

A psychologist named Oskar Pfungst tested him properly. Hans kept getting the answers right — but only when the person asking already knew the answer, and only when Hans could see them.

The explanation was better than the trick. As Hans approached the correct number of taps, the questioner's body changed almost imperceptibly: a slight lift of the head, a release of tension, a held breath let go. Hans wasn't counting. He was reading people, at a level of detail we barely register in ourselves.

That's the bit worth carrying to the yard. Your horse, pony or donkey is tracking your shoulders, your breathing, the grip on the lead rope. If you're braced for a spook at the gate, you have already told them something.

So before a clip, a trailer, a vet visit: sort yourself out first. Drop your shoulders, breathe out, walk like it's boring.

They were always going to notice. The only question is what you're saying. 🐴
